I did about 3 hour mtb activity and had 1/s gps setting on. It saved 11861 points. Activity was saved in explore android but failed to sync to explore web. It seems that activity is too large. I had another activity having about 9000 gps points and it was synced fine to explore web. Just wondering if there is some limit on those saved points to sync to web? Like 10000 gps points?
